        # subject_token` is an AWS token, it must be a serialized, [signed](https://docs.
        # aws.amazon.com/general/latest/gr/signing_aws_api_requests.html) request to the
        # AWS [`GetCallerIdentity()`](https://docs.aws.amazon.com/STS/latest/
        # APIReference/API_GetCallerIdentity) method. Format the request as URL-encoded
        # JSON, and set the `subject_token_type` parameter to `urn:ietf:params:aws:token-
        # type:aws4_request`. The following parameters are required: - **`url`**: The
        # URL of the AWS STS endpoint for `GetCallerIdentity()`, such as `https://sts.
        # amazonaws.com?Action=GetCallerIdentity&Version=2011-06-15`. Regional endpoints
        # are also supported. - **`method`:** The HTTP request method: `POST`. - **`
        # headers`**: The HTTP request headers, which must include: - **`Authorization`**
        # : The request signature. - **`x-amz-date`**`: The time you will send the
        # request, formatted as an [ISO8601 Basic](https://docs.aws.amazon.com/general/
        # latest/gr/sigv4_elements.html#sigv4_elements_date) string. This is typically
        # set to the current time, and used to prevent replay attacks. - **`host`**: The
        # hostname of the `url` field; for example, `sts.amazonaws.com`. - **`x-goog-
        # cloud-target-resource`**: The full, canonical resource name of the
        # WorkloadIdentityPoolProvider, with or without the HTTPS prefix. For example: ``
        # ` //iam.googleapis.com/projects//locations//workloadIdentityPools//providers/
        # https://iam.googleapis.com/projects//locations//workloadIdentityPools//
        # providers/ ``` Signing this header as part of the signature is recommended to
        # ensure data integrity. If you are using temporary security credentials
        # provided by AWS, you must also include the header `x-amz-security-token`, with
        # the value `[SESSION_TOKEN]`. The following is an example of a signed,
        # serialized request: ``` ` "headers":[ `"key": "x-amz-date", "value": "
        # 20200815T015049Z"`, `"key": "Authorization", "value": "AWS4-HMAC-SHA256+
        # Credential=$credential,+SignedHeaders=host;x-amz-date;x-goog-cloud-target-
        # resource,+Signature=$signature"`, `"key": "x-goog-cloud-target-resource", "
        # value": "//iam.googleapis.com/projects//locations//workloadIdentityPools//
        # providers/"`, `"key": "host", "value": "sts.amazonaws.com"` . ], "method":"
        # POST", "url":"https://sts.amazonaws.com?Action=GetCallerIdentity&Version=2011-
        # 06-15" ` ``` You can also use a Google-issued OAuth 2.0 access token with this
        # field to obtain an access token with new security attributes applied, such as
        # an AccessBoundary. In this case, set `subject_token_type` to `urn:ietf:params:

        # access tokens that already contain security attributes is not allowed.
